I’m running Ubuntu 18.04 and migrating my services to running in docker and using Traefik as a reverse proxy and with my own domain. I’ve configured the dns to cloudfare and ddclient seems to be updating the ip correctly.

The issue is when I start up traefik within the docker I get the following errors:

I’ve looked into each of the directories above and nothing points to duckdns anywhere. I’ve also done a recursive grep through all of my docker directories and likewise, nothing is referring to duckdns except in some log files (which I removed).

Update: So I checked my dynamic dns client updates and both are working. My duckdns.org domain is still pointing to my current IP as is my new domain xxx.net. I manually changed the duckdns ip to something other than my own and now I get:
